WBKR's Nashville Kat brought it up this morning on the Waking Crew Show with Moon & Chad.

She noticed it first last night while watching the ACMs.

What do you think?

Now, I realize speculation like this is hazardous (and, tacky) but Nashville Kat spoke with someone off the record and this is what the person said:

"Mike and Carrie hoped to get pregnant in 2013, but they decided to put it off. During the holidays they told friends and family that 2014 was going to be the year they had a baby. They are both finally ready now."

And Kat says, with Carrie turning 32 this year on top of already being in the best shape of her life, now certainly seems as good a time as any.

So, maybe there is a new little Fisher in the tank.
